The area hosts a diversity of plants and birds and, in the spring, there are a variety of orange, purple and yellow wildflowers. There are about 10 miles of flat and rolling hill multi-use trails for hiking, biking and equestrian use with views of the Pacific Ocean and San Francisco Bay on clear days. There are two main entrances and both have restrooms.
